As shown in fig. 1-6, an automatic application mechanism includes: a base 100 and a swing arm 200, the base 100 being hinged to a first drive element 110; one end of the swing arm 200 is hinged to the base 100, the other end of the swing arm 200 is provided with a first pinch roller 210, the first driving element 110 is hinged to the swing arm 200, the swing arm 200 is in linkage connection with the first driving element 110, and the first driving element 110 can enable the first pinch roller 210 to be floatably pressed through the swing arm 200.

The base 100 may be preferably a vertical plate, the first driving element 110 is preferably an actuating element capable of performing a telescopic action, such as an air cylinder or a hydraulic cylinder or a linear motor, and the first driving element 110 and the swing arm 200 are both arranged in an inclined manner, which is beneficial to smoothness of adhesion, the swing arm 200 can swing around one end hinged to the base 100, and the first driving element 110 can drive the swing arm 200 to swing (rotate), and when the swing arm 200 swings, the first pressing wheel 210 at the other end of the swing arm 200 can lift.

The automatic pasting mechanism can be applied to pasting of a tape or a film material, taking a tape pasting process as an example, the first driving element 110 drives the swing arm 200 to rotate downwards and enables the first pressing wheel 210 to press the tape to the surface of a product, then the automatic pasting mechanism moves relative to a workpiece so as to paste the tape to the surface of the product along a moving track, and in the moving process of the automatic pasting mechanism, the first driving element 110 applies constant pressure to the first pressing wheel 210 through the swing arm 200 so as to enable the tape to be tightly pasted to the surface of the product; once passing through the portion of the product with the height, the first pressing wheel 210 can float up and down, thereby adapting to the surface of the product with the height.

Here, since the swing arm 200 is linked to the first driving element 110, the first driving element 110 can drive the swing arm 200 to swing, and further press the first pressing wheel 210, but when the first pressing wheel 210 passes through a surface with undulated height, the swing arm 200 and the first driving element 110 will also correspondingly operate, so that the first pressing wheel 210 can float.

The mechanism can automatically paste the adhesive tape or the film on the surface of a workpiece at constant pressure, and can float when encountering the surface with high and low undulations on a product in the pasting process so as to adapt to the pasting surface with high and low undulations, thereby obtaining the high-quality pasting effect.

In order to enable the first driving element 110 to perform the function of floating compaction, the first driving element 110 is required to be provided as a first air cylinder, the base 100 is provided with a pressure reducing valve 140, the first air cylinder is connected with the pressure reducing valve 140, the first air cylinder can push the first compaction wheel 210 to descend through the swing arm 200 to perform compaction, and the first air cylinder passively acts when the first compaction wheel 210 passes through a rugged surface to enable the first compaction wheel 210 to float while keeping compaction.

Preferably, the first cylinder can be depressurized and adjusted to a suitable pressure by the pressure reducing valve 140, so that the first cylinder can provide a constant pressure to the first pinch roller 210 and can be depressurized during floating; it should be noted that the gas introduced into the first cylinder would not be depressurized through the depressurization valve 140, resulting in the first cylinder having too high a pressure to float.

Specifically, since the first cylinder has a floating effect through the pressure reducing valve 140, a piston rod of the first cylinder is hinged to the swing arm 200, and the first cylinder is adjusted to a proper pressure through the pressure reducing valve 140, it is ensured that the first cylinder can provide a sufficient pressing force and can float; when the first pressing wheel 210 passes through a relatively high position, the first pressing wheel 210 passively pushes the swing arm 200 to rotate, and then the piston rod of the first cylinder is pushed into the cylinder body, so that the first pressing wheel 210 floats upwards; when the first pinch roller 210 passes through a relatively low position, the piston rod of the first air cylinder extends again and pushes the swing arm 200 to rotate, so that the first pinch roller 210 floats downwards; according to the embodiment, the automatic pasting mechanism can adapt to the height and undulation surface of a product, and the consistency of pasting is ensured.
